Abstract
A resistive film type touch panel includes first and second resistive films respectively provided on the inner surfaces of a pair of substrates on the touch side and the opposite side, protruding contacts which are provided on the first resistive film so as to protrude to a predetermined height, and come into contact with the second resistive film upon bending/deformation of the touch-side substrate by a touch to electrically connect the touch-side substrate to the second resistive film, insulating spacers which are arranged between the substrates except the positions of the protruding contacts, and define the space between the substrates to a height higher than that of protruding contacts, and a liquid or liquid crystal sealed in the space between the substrates. This arrangement reduces the bending/deformation amount of the touch-side substrate and the refraction of transmitted light at a portion bent/deformed by a touch on the touch-side substrate.
